FIELD OF THE INVENTION

The present invention relates to a wheel cover, and more particularly, to a wheel cover for truck front wheels. The body of the wheel has multiple recesses and each recess has a washer whose diameter is smaller than that of the nut on the rim so that the wheel cover can be connected to different nuts of different rims.

BACKGROUND OF THE INVENTION

Generally, the hub, the bolts and the nuts of a truck front wheel are exposed from the outside of the rim, and a wheel cover is mounted to the outside of the rim to hide the hub, the bolts and the nuts. As shown in FIG. 1, the wheel cover 1 is used to hide the hub 2 and the bolts 21 and nuts 22 of the rim 2, and the wheel cover 1 generally comprises a body 10 which has a tapered protrusion 11 and a surface 12 is formed at the center of the protrusion 11. Multiple holes 13 are defined through the surface 12 so that the bolts 21 extend through the holes 13. Each bolt 21 is the connected with a nut 22 from outside of the body 10 so as to fix the wheel cover 1 to the rim 2. However, when assembling the wheel cover 1 to the rim 2, all of the nuts 22 are removed from the bolts 21, and the wheel cover 1 is mounted to the rim 2, and then all of the nuts 22 are connected to the bolts 21 again. Although the hub 20 and some of the bolts 21 can be hidden by the wheel cover 1, the nuts 22 and some of the bolts 21 are exposed. The tightness of the nuts 22 have to be checked to ensure that the nuts 22 do not loose.

Another wheel cover 3 is shown in FIG. 2 and has a body 30 with a protrusion 31 extending centrally from the outside thereof, and a surface 32 is formed at the central portion of the protrusion 31. At least two holes 33 are defined through the surface 32 and each hole 33 has a connection part 34 located therein. At least two connection members 35 are located at the inside of the body 30. One end of each connection member 35 is connected to the bolt 21 corresponding thereto, and the other end of each connection member 35 extends through the hole 33 of in the surface 32 and is connected to the connection part 34 corresponding thereto. The wheel cover 3 is fixed to the rim 2 by the at least two connection members 35 and the connection parts 34. Although the hub 20, the bolts 21 and the nuts 22 can be hidden by the wheel cover 3, the lengths of the bolts 21 extending from different rims 2 are different, when the wheel cover 3 is connected to the rim 2 by connecting the connection members 35 to the bolts 21, and the wheel cover 3 is secured by the connection parts 34, the length of the bolts 21 extending from some of the rims 2 is too short, so that the connection members 35 cannot firmly connected to the bolts 21. Therefore, the wheel cover 3 may be loosened or even drop off by the vibration when the truck is moving.

The present invention intends to provide a wheel cover for a front wheel of a truck and the wheel cover improves the shortcomings of the conventional ones.
